Heading abroad in the legal cannabis era could harsh your buzz

“No cannabis at border crossings.” The signs posted on the Canadian side of Ontario’s Thousand Islands crossing into the United States couldn’t be more clear. They’re punctuated with a logo featuring a pot leaf inside a red circle with a red slash through it.

As of Oct. 17, adults in Canada can possess and share up to 30 grams of legal cannabis. They’ll be able to buy it from provincially or federally licensed retailers and grow up to up to four cannabis plants per residence for personal use.
